Does this mean:

1. a system which believes it has an accurate idea what the current UTC time is, but doesn't know where it is on Earth (or where its operator conceptually wants it to pretend it is)?

2. Or a system which has had its clock set manually, but its TZ has never been set (therefore it has no idea what the UTC time is, and therefore cannot reliably generate or store a valid time with offset.

3. Or a system which knows both its clock and its TZ have never been set?

For the first one, it seems silly, since as long as you're recording correct timestamps, fixing the display timezone later is easy and nondestructive. For 2 it seems like the OS should require setting TZ to set a time. For 3, I suppose this is actually mildly useful, since it's easy for an OS to detect if you have inited the RTC from its original starting point, and specially flagging datetimes stored while it's in that state could help to clean them up later when the correct time is known.
